Double direction thrust ball bearings
LYNB thrust ball bearings are separable, i.e. the shaft washer, housing washer(s), ball and cage assembly(s) can be mounted separately. Shaft washers have a ground bore to enable an interference fit. The bore of the housing washer is turned and always larger than the shaft washer bore. LYNB thrust ball bearings are produced as single direction or double direction thrust ball bearings and angular contact thrust ball bearing. They are designed to accommodate axial loads only and must not be subjected to any radial load. 
  Double direction thrust ball bearings can carry axial loads in double directions, but it can not carry radial load. LYNB double direction thrust ball bearings can make an axial location in two directions. LYNB double direction thrust ball bearings also have planar housing washer and self-aligning seat washer. Generally, planar housing washer cannot allow any angular error, however, when designing bracing structures, a gap of 0.5~1mm between the outer diameter of housing washer and the fitting surface of bearing block can be kept to correct the angular errors, which, would be made when mounting. Self-aligning housing washer need to be ordered and manufactured separately.
LYNB can provide thrust ball bearings with other special structures, such as thrust ball bearings without cages, unidirectional thrust ball bearings with taper bores, unidirectional thrust ball bearings with steel wire raceway and etc. All the types cannot be listed in this catalogue. 
 ▲ LYNB can design and manufacture many other similar structures in accordance to the special and particular requirements of their customers’. If our customer’s have specific requests then the customer should identify the structure, and mounting dimensions that are required.
